Identification Guide
Identifying the prickly cockle (Acanthocardia echinata) involves noting specific physical traits, comparing it to similar species, and understanding its unique features. This guide provides essential details to help with recognition and classification.How to Identify a Prickly Cockle
To identify a prickly cockle, one should first observe its size and shape. Adults typically reach up to 60mm in length and are plump and rounded. The shells are characterized by strong, radial ribs. These ribs can number about 20 on larger specimens. Additionally, juvenile shells tend to have fewer ribs. Another key point is the presence of coarse concentric striations that run between the ribs. These features help in distinguishing this species from others.Characteristics
The prickly cockle has a distinctive appearance. The shell is thick and somewhat glossy with a brown or gray color. The interior of the shell can be reflective and white or purple in hue. They have a symmetrical shape, typically high and rounded. The surface texture is rough due to the prominent ribs, which add to its prickly appearance. Furthermore, these clams often inhabit sandy or muddy substrates in saltwater environments, which is useful for habitat identification as well.Comparison to Similar Species
When comparing the prickly cockle to similar species, two clams stand out: the cockle (family Cardiidae) and the common heart cockle (Corculum cardissa). Both share similar environments and can often be found near each other. Key differences include:- Rib Number: Prickly cockles have about 20 ribs, while others may have more or less.
- Shape: The prickly cockle is more rounded compared to the heart cockle, which is usually flatter.
